Hayley Brehaut wants to save hundreds of lives.
But she is not a superhero, or a surgeon.
She is an advocate for organ donation.
For her "passion project" at Unity College, the year 9 student hopes to inspire 100 people to register as organ donors.
"Not many people realise how rare (organ donation) is," she said.
"There are two types of death, brain and circulatory; it only works when with brain death and you have to die in a hospital.
"There are so many factors that need to happen before the operation can take place."
On social media, she has begun challenging her friends to "donate life today" by registering at the website donatelife.gov.au, and to share the message with three more people.
She also made and put up a display at her netball club.
She believed about 30 people had signed up as a result of her efforts.
Her interest in organ donation was partly inspired by former Unity student Alex Aunger, who saved several lives by allowing his organs to be donated following his death from meningococcal disease in 2012.
He was 18 years old.
"His heart went to a mother of three and his liver was split in two; half of his liver went to a two-year-old girl," Hayley said.
"I would like to thank the Aunger family for their support throughout my project."
In 2018, 1782 Australians' lives were transformed when they received organs from 554 deceased and 238 living donors, according to the national Organ and Tissue Authority.
Another 1400 are waiting for a donation.
More than 10,500 people benefited from eye or tissue donations last year.
